GHSA-8r88-6cj9-9fh5
auth-js Vulnerable to Insecure Path Routing from Malformed User Input
Quick fix
GHSA-8r88-6cj9-9fh5 — @supabase/auth-js: upgrade to the fixed version with the command below.
npm install @supabase/auth-js@2.70.0Details
### Impact The library functions `getUserById`, `deleteUser`, `updateUserById`, `listFactors` and `deleteFactor` did not require the user supplied values to be valid UUIDs. This could lead to a URL path traversal, resulting in the wrong API function being called.
Implementations that follow security best practice and validate user controlled inputs, such as the `userId` are not affected by this.
### Patches Strict value checks have been added to all affected functions. These functions now require that the `userId` and `factorId` parameters MUST be valid UUID (v4).
**Patched version:** >= 2.69.1
### Workarounds Implementations that follow security best practice and validate user controlled inputs, such as the `userId` are not affected by this. It is recommended that users of the auth-js library always follow security best practice and validate all inputs, before passing these to other functions or libraries.
